got some kc42 brains a while ago and they are almost three weeks old now... im not sure if im smelling soil or weed yet because the odor is pretty soft, but how long should i expect before the smell becomes noticeable?
I've grown a dozen or more different strains and I noticed the smell sooner in some then others.
Like this tangerine dream, They are three weeks and smell when you move them now. Train Wreck was like that too.
So I would say it depends on the strain and how often you move them.
